      I brought LG LED 124cm 49UK7500  UHD/4K from India to UK. Will the TV support UK TV channels such as BBC and others through a TV Aerial cable or do i need to buy a FreeView box?

      Hi, I'm curious if anyone else is seeing this annoying new behaviour.
      I have my SKY Q box on HDMI1 and have become accustomed to switching back from Netflix (or any other app for that matter) by having HDMI1 assigned to button "1" using the Quick Access feature.  In the last week though, this feature has stopped working properly. If I am in Netflix and I press the "1" button, nothing happens (as expected). If instead I hold down the "1" button to switch to SKY I get a pop up that says this: "Do you want to add Netflix to [Quick Access 1]?".   If I then hold down the "0" button, the 3x3 grid "EDIT QUICK ACCESS" pop-up appears and I can clearly see my SKY Q/HDMI 1 in the top left grid position (button "1")!!!
      If I then switch via the Home button to HDMI1 and remove HDMI1 from Quick Access (via the  EDIT QUICK ACCESS pop up), I can then re-add it by holding down 1 or from within the pop-up. Now, if I go into Netflix and then hold down 1, my TV does (correctly) switch to HDMI1. Hurrah! If however I turn my TV off and back on, then go to Netflix, then hold down "1", I am back to square one with the question "Do you want to add Netwflix to [Quick Access 1]?"......Grrrr!!!
      I have tried switching the TV off at the wall, leaving for 10 seconds and repowering, which doesn't fix the problem (I don't believe WebOS reboots when you do this). LG appear to have made it a practical impossibility to reboot WebOS via anything other than a factory reset which I don't really want to do as it'll take me too long to get all my settings back to where I have them now. Some blogs suggest that the "User Licence agreement" setting can be changed which forces a reset from within the General tab but I don't see this on my TV (guessing that WebOS interface has changed).
      Anyone have any ideas? 
      Rob.

      Our current app is available on 4K/UHD LG television models running the following system software:
      webOS 3.0 webOS 3.5 webOS 4.0 webOS 5.0 No 720p or 1080p (“full HD”) sets are supported for our current app at this time.
      Note: Due to root certificate limitations with the device OS itself, only webOS 5.0+ devices support secure connections with a personal Plex Media Server. To allow connections to a personal server, devices running earlier webOS versions must be set to Allow Insecure Connections in the TV app settings and the Plex Media Server must be set to Preferred for the Secure Connections preference.
